 #. The values of the ``planning_adapters`` is the order in which the mentioned adapters are called / invoked. Order here matters. Inside the CHOMP adapter, a :moveit_codedir:`call <moveit_planners/chomp/chomp_optimizer_adapter/src/chomp_optimizer_adapter.cpp#L169>` to OMPL is made before invoking the CHOMP optimization solver, so CHOMP takes the initial path computed by OMPL as the starting point to further optimize it.
